CAP1133

3 Channel Capacitive Touch Sensor with 3 LED Drivers

General Description

Features

The CAP1133, which incorporates RightTouch^®tech-

nology, is a multiple channel Capacitive Touch sensor

with multiple power LED drivers. It contains three (3)

individual capacitive touch sensor inputs with program-

mable sensitivity for use in touch sensor applications.

Each sensor input automatically recalibrates to com-

pensate for gradual environmental changes.

• Three (3) Capacitive Touch Sensor Inputs

- Programmable sensitivity

- Automatic recalibration

- Individual thresholds for each button

• Proximity Detection

• Multiple Button Pattern Detection

• Calibrates for Parasitic Capacitance

• Analog Filtering for System Noise Sources

The CAP1133 also contains three (3) LED drivers that

offer full-on / off, variable rate blinking, dimness con-

trols, and breathing. Each of the LED drivers may be

linked to one of the sensor inputs to be actuated when

a touch is detected. As well, each LED driver may be

individually controlled via a host controller.

• Press and Hold feature for Volume-like Applica-

tions

• SMBus / I²C Compliant Communication Interface

• Low Power Operation

The CAP1133 includes Multiple Pattern Touch recogni-

tion that allows the user to select a specific set of but-

tons to be touched simultaneously. If this pattern is

detected, then a status bit is set and an interrupt gen-

erated.

- 5uA quiescent current in Deep Sleep

- 50uA quiescent current in Standby (1 sensor

input monitored)

- Samples one or more channels in Standby

• Three (3) LED Driver Outputs

Additionally, the CAP1133 includes circuitry and sup-

port for enhanced sensor proximity detection.

- Open Drain or Push-Pull

- Programmable blink, breathe, and dimness

controls

The CAP1133 offers multiple power states operating at

low quiescent currents. In the Standby state of opera-

tion, one or more capacitive touch sensor inputs are

active and all LEDs may be used.

- Can be linked to Capacitive Touch Sensor

inputs

• Available in 10-pin 3mm x 3mm RoHS compliant

DFN package

Deep Sleep is the lowest power state available, draw-

ing 5uA (typical) of current. In this state, no sensor

inputs are active. Communications will wake the

device.

Applications

• Desktop and Notebook PCs

• LCD Monitors

• Consumer Electronics

• Appliances
